A rectangular prism is a 3D shape like a box. To understand it better, we count its parts: faces (flat sides), edges (where the faces meet), and vertices (corners). Think of a cereal box! Counting these parts helps us describe and compare different 3D shapes.
Let's practice counting the faces, edges, and vertices of rectangular prisms with this worksheet! You'll be a 3D shape expert in no time!
Match the words with their correct definitions:
| Word | Definition |
|---|---|
| 1. Vertex | A. A flat surface of a 3D shape. |
| 2. Edge | B. The point where edges meet. |
| 3. Face | C. The line segment where two faces meet. |
| 4. Rectangular Prism | D. A 3D shape with six rectangular faces. |
| 5. 3D Shape | E. An object that has height, width and depth. |
Read the paragraph and fill in the missing words:
A rectangular prism has six __________, twelve __________, and eight __________. Each __________ is a corner where the edges meet. The __________ are the flat surfaces.
Imagine you're building a rectangular prism out of straws and clay. The straws are the edges, and the clay balls are the vertices. How many straws and clay balls would you need? Explain your answer.
